Security Fix(es):
* A use-after-free vulnerability was found in the kernels socket recvmmsg
subsystem. This may allows remote attackers to corrupt memory and may allow
execution of arbitrary code. This corruption takes place during the error
handling routines within __sys_recvmmsg() function. (CVE-2016-7117,
Important)
Bug Fix(es):
* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got
in some cases rebooted during the graceful node failover test, because the
host kept sending heartbeat packets independently of guests responding to
them. This update fixes the bug by properly responding to all the heartbeat
messages in the queue, even if they are pending. As a result, guest VMs no
longer get rebooted under the described circumstances. (BZ#1391167)");
